Bigororotse
Igororotse-binyuze kuri Ethernet Switches irashobora kumvikana nkumurongo wa matrix hamwe numurongo wa crisscross hagati yibyambu. Iyo igipaki cyamakuru kigaragaye ku cyambu cyinjiza, Umutwe w'ipaki ugenzuwe, aho ugana kumeza wabonetse, imbonerahamwe y'imikorere y'imbere iratangira, kandi icyambu gikwiranye cyarahindutse. Igipaki cyamakuru gihujwe ninjiza yinjiza nibisohoka, kandi paki yamakuru ifitanye isano itaziguye nicyambu gihuye kugirango tumenye imikorere yo guhinduranya. Kuberako bidakenewe kubikwa, gutinda ni gito cyane kandi guhinduranya birihuta cyane, ninyungu zacyo. Ingaruka ni uko kuva ibikubiye muri paki yamakuru idakijijwe na Ethernet Show, ntibishoboka kugenzura niba paki yamakuru yatangiriye nabi, kandi ubushobozi bwo gutahura amakosa ntashobora gutangwa. Kuberako nta casho, kwinjiza / gusohoka ibyambu byumuvuduko utandukanye ntibishobora guhuzwa mu buryo butaziguye, kandi biroroshye gutakaza.
Ububiko no imbere
Ububiko nuburyo bwo imbere nuburyo bwo gusaba mumwanya wumuyoboro wa mudasobwa. Irabanza kubika paki yamakuru yicyambu cyinjiza, noneho ikora CRC (CRC ya Redection ya CRC (ifata icyemezo cya Packet ya Data nyuma yo kohereza ikibanza cyibisohoka mumeza. Kubera iyo mpamvu, gutinda kubika no kohereza mu gutunganya amakuru ari binini, bikaba bidatinze, ariko birashobora gutahura amapaki yamakuru yinjira kandi atezimbere imikorere. By'umwihariko ni uko bishobora gushyigikira guhinduka hagati yibyambu byumuvuduko utandukanye kandi ugakomeza ibikorwa byubufatanye hagati yibyambu byihuta cyane hamwe nibyambu byihuta.
Gutandukana
Iki nikisubizo kiri hagati yabiri. Iragenzura niba uburebure bwa paki yamakuru irahagije kuri 64 bytes. Niba ari munsi ya 64 bytes, bivuze ko ari paki yimpimbano kandi paki irajugunywa; Niba birenze kuri 64 bytes, paki yoherejwe. Ubu buryo ntabwo butanga amakuru. Umuvuduko wamakuru wayo wihuta kuruta ububiko no kohereza, ariko buhoro kuruta pass itaziguye. Kumenyekanisha guhinduranya umusikubaho.
Muri icyo gihe, himbman switch irashobora kohereza amakuru hagati yibyambu byinshi. Buri cyambu gishobora gufatwa nkumuyoboro wigenga wumubiri (Icyitonderwa: Igicapo c'ibice kitari IP), hamwe nibikoresho bya Network bihujwe nabyo birashobora kwishimira igitambaro cyose utigenga udahanganye nibindi bikoresho. Iyo node yohereje amakuru kuri node d, node b irashobora kohereza amakuru kuri node c icyarimwe, kandi byombi bifite umurongo wuzuye wumuyoboro kandi ufite isano yabo. Niba ethernet ya 10MBST yakoreshejwe, traffic yose ya switch ihwanye na 2x10MBPS = 20MBPS. Iyo 10Mbps isangiye hub ikoreshwa, traffic zose za hub ntizarenga 10Mbps.
Muri make, theHirschmanni igikoresho cyurusobe rushobora kuzuza imikorere yo gutandukana no kohereza amakadiri ashingiye kuri adresse ya MAC. Guhindura amashusho birashobora kwiga aderesi ya MAC hanyuma ubibike mumagambo yimbere, kandi ugera ku ntego binyuze mu guhindura by'agateganyo hagati y'umutavugamo hamwe n'intego yakira amakuru.
